8583ef1822 Pack all global video-related variables into a structure for clarity.
A comment said that they weren't in a struct for speed reasons but...
this should not affect performance because these variables are mostly
used to set other variables (hence they are read few times).

9220353379 Move the definition of multiple video-related variables into a new
header file (machine/video.h) so that we can kill all the "manual"
externs spread around the code (which were inconsistent among them).

2b47cc7981 Split the global videosize variable into videowidth and videoheight:
makes the code clearer and avoids multiple parts of it having to know
how videosize was encoded.

66fefd117b It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

aa9fb9663f Switch mac68k's sn(4) Ethernet to MI SONIC driver.
Tested with Apple Ethernet CS Twisted-Pare Card on LC630 by me
and Quadra 650 on-board Ethernet by hauke@.
NuBus based cards and PowerBook variants are still untested.

4dfb61f1c6 Previous fix is not correct. sc_dmaaddr is actually
pointer against pointer, so just use proper casts
rather than bogus void pointers.

142c2a33ba Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.

bf1a4d2af5 properly use ata_channel->ch_ndrive:
- initialize it properly in the bus front-ends (all 2, exept in wdc_pcmcia.c
  for the "Sandisk CompactFlash Card" where it's set to 1)
- remplace hardcoded '2' by ata_channel->ch_ndrive in MI IDE drivers.

aec75b1cc6 - change the way to specify a bufq strategy. (by string rather than by number)
- rather than embedding bufq_state in driver softc,
  have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
  from sys/bufq.h to sys/bufq_impl.h.
  (is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c.  (not tested)

4b51cecfc2 - Split the register handles out of struct wdc_channel into a separate
wdc_regs structure, and array of which (indexed per channel) is pointed
  to by struct wdc_softc.
- Move the resulting wdc_channel structure to atavar.h and rename it to
  ata_channel.  Rename the corresponding flags.
- Add a "ch_ndrive" member to struct ata_channel, which indicates the
  maximum number of drives that can be present on the channel.  For now,
  this is always 2.  Add an ATA_MAXDRIVES constant that places an upper
  limit on this value, also currently 2.

2ecdd552dc Add the notion of "shadow registers" to the wdc driver. These shadow
registers are registers that overlap with others on many controllers, but
which may actually be distinct on some controllers.  Right now, the two
shadows are:

- wd_status (usually overlaps wd_command)
- wd_features (usually overlaps wd_error)

Add a new helper function, wdc_init_shadow_regs(), used to initialize
the shadow register handles on controllers where they do actually overlap.

d19528e4e0 Adapt to MI ATA/wdc changes. Especially, now that the address of
each individual ATA register is in the attachment structure, we
can dispense with the custom bus_space mapping hack which set the
stride, then unset it for particular bus_space functions. (There
is really no stride; the data register is read and written to
consecutive bytes. The control register mappings just happen to
be separated by four bytes.) While we're here, de-__P(), and lose
a confusing shift.

This has been tested on Quadra 630. Reviewed by bouyer.
